WUE is the Western Undergraduate Exchange, a program coordinated by the Western Interstate Commission for Higher Education (WICHE). Through WUE, students in Western states may enroll in participating two-year and four-year public college programs at a reduced tuition level: up to 150 percent of the institution’s regular resident tuition. In all cases, WUE tuition is considerably less than nonresident tuition. Here a list of universities that participate in the program:
